Belgian Journal of Entomology 18 : 1-34 (2014) New Tachydromiinae (Diptera: Empidoidea: Hybotidae) from different types of forests along the Congo river (D. R. of the Congo) Patrick GROOTAERT 1 & Igor SHAMSHEV 2 1 Entomology, Royal Belgian Institute of Natural Sciences, Rue Vautier 29, B-1000, Brussels, Belgium (e-mail: Patrick.Grootaert@naturalsciences.be) 2 All-Russian Institute of Plant Protection, shosse Podbel skogo 3, 188620, St. Petersburg, Russia. Temporary address: Royal Belgian Institute of Natural Sciences, Brussels (e-mail: shamshev@mail.ru) Abstract Different types of forest under different human pressure were investigated for the diversity of Tachydromiinae (Diptera: Hybotidae) in the D. R. Congo. Forty one species were recorded. Thirteen species are new for science: Drapetis denticulata sp. nov., D. yangambensis sp. nov., Elaphropeza albistylus sp. nov., E. aseta sp. nov., E. asquamata sp. nov., E. dudui sp. nov., E. elasii sp. nov., E. kinshasensis sp. nov., E. leponcei sp. nov., E. pachystylus sp. nov., E. pulchra sp. nov., E. verheyeni sp. nov. and E. wetsii sp. nov. All species are described and male genitalia illustrated. Keys for Drapetis and Elaphropeza (GROOTAERT & SHAMSHEV, 2013) have been updated to include the new species described here. Crossopalpus nyaka Smith, 1969 described from South Africa is reported for the first time in D. R. Congo. It is re-described and illustrated. Females of Drapetis congoensis Grootaert & Shamshev, 2013 and D. yaekelaensis Grootaert & Shamshev, 2013 are described for the first time. 24 barcodes of the COI gene from 14 species recorded in this study have been generated and are available at GenBank. Keywords: Diptera, Hybotidae, Tachydromiinae, new species, D. R. Congo. Introduction The present paper is the result of a short sampling campaign in the first half of June 2012 in the surroundings of Yangambi (D. R. Congo, Oriental Province). Here we limit ourselves to describe the new Tachydromiinae found in the samples, simply because almost no Hybotinae were collected during the campaign. Collections were made in a gradient of forest types ranging from garden patches, bamboo, over young forest to mixed primary and monodominant Gilbertiodendron forest. The study was in the scope of the PODO project COBIMFO (Congo Basin Integrated Monitoring for Forest Carbon Mitigation and Biodiversity) in which a relation is being sought between carbon fixation and biodiversity. The aim of this project is to get baseline reference data on the Carbon balance and biodiversity in pristine and intervened dense tropical forests of the Congo Basin and to increase our understanding of the relationship between both variables as a function of forest management. The present work is a supplement to the monograph published by GROOTAERT & SHAMSHEV (2013) on the Hybotidae collected during the Boyekoli Ebale Congo 2010 Expedition. During that expedition collections were made at the beginning of the dry season in wet to very wet forest a little West of the present survey in Yangambi. In Yangambi the forest soil was much drier and collections were made a little later in the dry season. The descriptions of a few species collected in a garden (park) in Kinshasa are added in order to see the differences between sites with strong human impact and with less human perturbation. Barcodes of most hybotid species described by GROOTAERT & SHAMSHEV (2013) and the new Tachydromiinae from the present paper have been published in GenBank (NAGY et al., 2013). 3

GROOTAERT P. & SHAMSHEV I. New Tachydromiinae from D. R. Congo Material and methods The material is housed in the Collections of the Biodiversity Centre (Centre de Surveillance de la Biodiversité) in Kisangani (D. R. Congo), while voucher specimens are deposited in the Royal Belgian Institute of Natural Sciences, Brussels, Belgium (RBINS). In the descriptions we cite under reg. the register number that is a unique identifier referring to the locality, date and microhabitat. When we cite the holotype we indicate also the MS name or code that was used throughout the description process e.g. EC4 is the fourth Elaphropeza species found in the Congo samples. All specimens were collected by the first author (PG) and are conserved in 70% alcohol. The specimens from which DNA was extracted are conserved in our tissue collection with the cuticular parts still being recognisable. We refer to the barcode of the tube in the tray in which it is conserved; e.g. tube AB31515301 stored in tray called Congo2. The terminology and descriptive format used in the descriptions follow GROOTAERT & SHAMSHEV (2012). In describing the sclerites of the thorax the terminology used by previous authors is often indicated in brackets. The scale bar represents 0.1 mm, but this is only an indicative measure because the drawings are projections of structures that are usually not in a horizontal plane. The following abbreviations are used in the illustrations: a: apodeme; hy: hypandrium; lc: left cercus; le: left epandrial lamella; ls: left surstylus; ph: phallus; rc: right cercus; re: right epandrial lamella; rs: right surstylus. Systematics Family HYBOTIDAE Subfamily Tachydromiinae Genus Crossopalpus Bigot, 1857 REMARKS. Currently the world fauna of Crossopalpus numbers 84 species. Seventeen species are known from the Afrotropical Realm (3 from D. R. Congo). RAFFONE (1994) provided a key to the Afrotropical species of Crossopalpus. GROOTAERT & SHAMSHEV (2013) reported 4 species from D. R. Congo: one new species, records for two previously described species and an unnamed female. Here below we report on a species described from South Africa C. nyaka Smith, 1969. Crossopalpus nyaka Smith, 1969: 35, Fig. 36. Crossopalpus nyaka Smith, 1969 (Figs 1 3) MATERIAL EXAMINED: D. R. Congo: Kinshasa, 3, 2, large garden in city centre, 3 June 2012 (reg. 32001; leg. P. Grootaert; MS reference Crosso 4). A complete female in tray Congo 2 at position E7 with barcode AB42405565 and a complete male in tray Congo2 at position E6 with barcode AB42405559 were extracted for DNA and a COI barcode is available at GenBank. DIAGNOSIS. Medium-sized (about 2.0 mm) black species with yellow legs including all coxae, only apical tarsomere of all legs darkened; male hind basitarsus with brownish stripe ventrally on basal half (not in female). Antenna with scape and pedicel yellow, postpedicel brown; pedicel with long yellow ventral seta. Palpus yellowish. DESCRIPTION. Since SMITH (1969) made a detailed description we only give here some clarifications to conform with the current style of description. Male. Head: antenna with postpedicel nearly 1.5 times as long as wide; stylus about 5.0 times as long as postpedicel. Thorax: prothoracic episterna with long upturned seta just above fore coxa. 4

Belgian Journal of Entomology 18 : 1-34 (2014) Legs: hind basitarsus with narrow, brownish, ventral stripe on about basal half. Wing normally developed, uniformly finely infuscate. Costal bristle moderately long, brownish yellow. Costal index: 50/27/34. Vein R 2+3 evenly bowed. Veins R 4+5 and M 1+2 somewhat convergent near wing apex, R 4+5 slightly bowed, M 1+2 somewhat undulate. Crossvein bm-cu oblique. Crossvein r-m near middle of cell bm. Halter yellow. Abdomen: tergite 1 pale, tergite 2 unmodified; tergite 3 slightly broader than other tergites, with 2 small posteromarginal excisions dorsally; tergites 4 5 with similar excisions and also weaker sclerotised medially; tergites 6 7 weakly sclerotised; setation ordinary, minute; sternites undivided. Gland-like structure between tergites 3 4 and 4 5. Terminalia (Figs 1 3) small, brown. Cerci separated; right cercus very narrow; left cercus large, with broadened tip bearing long setae. Epandrium completely divided. Right surstylus represented by 2 sclerites, with short unmodified setae. Left epandrial lamella fused to hypandrium, lacking setation apically. Left surstylus represented by 2 small sclerites (Fig. 9), with short unmodified setae. Hypandrium narrow, attenuated apically, with long, narrow gonocoxal apodeme. Phallus short. Two rod-shaped apodemes. Female. Hind basitarsus entirely yellow; abdominal tergites 3 7 normally sclerotised, subrectangular; gland-like structures not prominent; tergite 8 dark brown, short, with sclerites separated; cercus small, subglobular, brownish yellow. REMARKS. Our specimens fit very well with the description given by Smith (1969). In our specimens the wing is faintly brownish tinged but was described as clear in the South African specimens. Finally, Smith (l.c.: Fig. 36) did not figure the long setae on the left cercus. In having legs almost entirely yellow (at most last tarsomere darkened) C. nyaka is similar to C. montalentii Raffone, 1994 described from Sierra Leone (Raffone, 1994). However, the latter has a strong anteroventral bristle on the hind tibia. DISTRIBUTION. South Africa (Natal), D. R. Congo. Figs 1 3. Crossopalpus nyaka Smith, 1969, 1.

Segment 8 rather short; cercus subglobular, brownish yellow. REMARKS. GROOTAERT & SHAMSHEV (2013) described this species after a male only. Among new materials taken from D. R. Congo a female of D. yaekelaensis was found. Genus Elaphropeza Macquart, 1827 REMARKS. Elaphropeza is the second largest genus of Tachydromiinae after Platypalpus and the largest among Drapetini genera. It has a circumtropical distribution and currently includes 212 named species worldwide. In the Afrotropics Elaphropeza remains poorly studied with only 40 known species (excluding the 11 new species described here) (GROOTAERT & SHAMSHEV, 2013). However, it is evident from the large amount of material from different parts of the Afrotropics which we have seen, but which cannot be treated here, that this group is very diverse in this region and many new species await description. We describe here 11 new species from the D. R. Congo and, thus, we increase the number of Afrotropical species of Elaphropeza to 51. SHAMSHEV & GROOTAERT (2007) arranged all species of Elaphropeza into two informal species groups, namely the E. ephippiata and E. biuncinata groups, keyed below. We follow that subdivision here again. Updated key to species of Elaphropeza from D. R. Congo 1. Proepisternum with long upturned bristle just above fore coxa.
